Benefits of technology

[0011]Still other advantages of various embodiments will become apparent to those skilled in this art from the following description wherein there are shown and described exemplary embodiments of this invention simply for the purposes of illustration. As will be realized, the invention is capable of other different aspects and embodiments without departing from the scope of the invention. Accordingly, the advantages, drawings, and descriptions are illustrative in nature and not restrictive in nature.

Problems solved by technology

Such light sources cannot function when the power supply is absent or interrupted.
In addition, many emergency light devices have complicated installation procedures, take up additional space, and do not have an aesthetic appearance or shape.
Accordingly, what is needed is a lighting power source that can function when the power supply is interrupted, but is easily installed and unobtrusive, and usable with a variety of existing lamps.

Embodiment Construction

[0017]Referring now in more detail to the drawings in which like parts have like identifiers, FIG. 1 shows a side view of an exemplary embodiment of a power outage socket device 10 installed on a standard desk or table lamp 2 with a light bulb 4 as the light source, with a lamp shade 6. The lamp 2, light bulb 4, and lamp shade 6 may be of any configuration known in the art, and during normal operation, power is supplied by a standard AC plug (not shown) or other power means known in the art.

[0018]As shown in FIGS. 1-5, the power outage socket device 10 is generally cylindrical, with a top 12 and a bottom 14, although the device 10 may be some other shape, including, but not limited to, a box or globe. The bottom 14 of the power outage socket device 10 has an externally threaded male connector 20 adapted to mount within the light socket 8 of the lamp 2, in place of the light bulb 4. The male connector 20 may extend from the surface of the bottom 14, or may be partially or wholly rece...

Abstract

A power outage socket device that may be installed on a variety of lamps or light fixtures. The bottom of the device has a male connector adapted to be inserted into the light socket on the lamp or light fixture, in place of the light bulb. A female socket adapted to receive the light bulb is located on the top of the device. The male connector may be recessed. When power is interrupted, emergency power is provided to one or more emergency light sources on the device to provide light. Emergency power is provided by one or more batteries, which may be rechargeable. The device also may include means for connecting a lamp harp, or for allowing a lamp harp to pass through the device. A photoelectric light sensor may be used to detect ambient light and control whether emergency light is provided when normal power is interrupted.

Description

TECHNICAL FIELD[0001]The present invention relates to lighting devices and sockets. More particularly, the present invention relates to a light socket system that can function when there is a power failure.BACKGROUND OF THE INVENTION[0002]Conventional light sources are reliant upon the availability of an external power supply. Such light sources cannot function when the power supply is absent or interrupted.[0003]It is known in the art to provide back-up lighting in the event of a power failure. Many such lighting systems, however, must be hardwired and installed by a professional electrician or person with similar training and skills. In addition, many emergency light devices have complicated installation procedures, take up additional space, and do not have an aesthetic appearance or shape. And many such systems provide a light source separate from the normal light source that functions when the power supply is available.[0004]Accordingly, what is needed is a lighting power source...
